Q. How do I cite an image in APA formate?
Do you mean an image from a website and you want to cite it on the References page? If so, Purdue OWL gives an example at the bottom of on page 4 and it continues to page 5 https://owl.english.purdue.edu/media/pdf/20110928111055_949.pdf
APA is the middle col.
Or perhaps you are looking for something like the 2nd example on this page. http://blog.apastyle.org/apastyle/2010/04/theres-an-art-to-it.html
As you look down the page you can see that you can change what is in the [ ] to the type of image such as photograph, sculpture, etc.
Here is a guide from another college that might help you. http://libguides.monroecc.edu/content.php?pid=210717&sid=1760065
